Abstract
Description
- The present disclosure relates to an apparatus and method for manufacturing cut reconstituted tobacco.
- Recently, in addition to tobacco leaves, reconstituted tobacco leaves have been used for the production of tobacco products. Reconstituted tobacco leaves are usually manufactured from parts of tobacco plants, such as tobacco stems or tobacco powder, that are less suitable for the production of cut fillers. In general, tobacco powder is produced as a byproduct during a manufacturing process of tobacco leaves.
- Common forms of reconstituted tobacco are reconstituted tobacco sheets or cast leaves. In a process of forming reconstituted tobacco sheets, tobacco powder and a binder are mixed to form a slurry, a tobacco web is created using the slurry, and a viscous slurry is casted onto a moving metal belt to manufacture a cast leaf. Alternatively, a slurry having low viscosity and high moisture content can be used to manufacture reconstituted tobacco in a process similar to a papermaking process.
- The reconstituted tobacco sheets can be cut to manufacture cut reconstituted tobacco. The cut reconstituted tobacco may be generated by finely chopping reconstituted tobacco sheets. When the reconstituted tobacco sheets are compressed to manufacture cut reconstituted tobacco, the density of the reconstituted tobacco sheets is increased, so the reconstituted tobacco sheets have hard pad forms, which makes it difficult to manufacture the cut reconstituted tobacco having suitable characteristics when the reconstituted tobacco sheets are cut.
- Accordingly, a method of effectively manufacturing cut reconstituted tobacco from reconstituted tobacco sheets is required.
- Provided is an apparatus and method for manufacturing cut reconstituted tobaccos, whereby cut reconstituted tobaccos is manufactured from reconstituted tobacco sheets by sequentially cutting the reconstituted tobacco sheets using a plurality of cutters. A technical problem to be achieved according to one or more exemplary embodiments is not limited to the above-described technical problem, and other technical problems may be inferred from the following exemplary embodiments.
- Provided is an apparatus for manufacturing cut reconstituted tobacco, the apparatus being based on a method whereby: a flavoring solution is supplied on an initial reconstituted tobacco sheet by using a flavoring apparatus; a plurality of intermediate reconstituted tobacco sheets are manufactured by cutting the initial reconstituted tobacco sheet using a primary cutter, a plurality of reconstituted tobacco strands are manufactured by cutting the plurality of intermediate reconstituted tobacco sheets in the longitudinal direction using a plurality of secondary cutters; and a plurality of pieces of cut reconstituted tobacco are manufactured by cutting the plurality of reconstituted tobacco strands in a transverse direction using a plurality of tertiary cutters.
- According to the present disclosure, in order for reconstituted tobacco strands manufactured from a reconstituted tobacco sheet supplied via a feed roller to have uniform quality, first, the initial reconstituted tobacco sheet is cut into a plurality of intermediate reconstituted tobacco sheets having smaller widths using the primary cutter and then each of the intermediate reconstituted tobacco sheets is cut in the longitudinal direction using the secondary cutters, so that a plurality of reconstituted tobacco strands may be manufactured.
- In addition, a plurality of secondary cutters are used so that, even when some of the secondary cutters have a defect, a process may be performed using the remaining secondary cutter without stopping the process.
- Also, a flavoring solution for secondary flavoring (top flavoring) is supplied onto the initial reconstituted tobacco sheet using a flavoring apparatus, thereby preventing the material for secondary flavoring (top flavoring) from being thermally deformed or lost.
- Furthermore, a plurality of pieces of cut reconstituted tobacco manufactured from a plurality of apparatuses for manufacturing cut reconstituted tobacco may be mixed using a plurality of conveyor units having different moving directions without using an additional blending device.

FIGS. 1 through 3 are diagrams showing examples in which a cigarette is inserted into an aerosol generating device. - Referring to
FIG. 1 , theaerosol generating device 10000 may include abattery 11000, acontroller 12000, and aheater 13000. Referring toFIGS. 2 and3 , theaerosol generating device 10000 may further include avaporizer 14000. Also, thecigarette 20000 may be inserted into an inner space of the aerosol generatingdevice 10000. -
FIGS. 1 through 3 illustrate components of theaerosol generating device 10000, which are related to the present exemplary embodiment. Therefore, it will be understood by one of ordinary skill in the art related to the present exemplary embodiment that other general-purpose components may be further included in theaerosol generating device 10000, in addition to the components illustrated inFIGS. 1 through 3 . - Also,
FIGS. 2 and3 illustrate that theaerosol generating device 10000 includes theheater 13000. However, according to necessity, theheater 13000 may be omitted. -
FIG. 1 illustrates that thebattery 11000, thecontroller 12000, and theheater 13000 are arranged in series. Also,FIG. 2 illustrates that thebattery 11000, thecontroller 12000, thevaporizer 14000, and theheater 13000 are arranged in series. Also,FIG. 3 illustrates that thevaporizer 14000 and theheater 13000 are arranged in parallel. However, the internal structure of theaerosol generating device 10000 is not limited to the structures illustrated inFIGS. 1 through 3 . In other words, according to the design of theaerosol generating device 10000, thebattery 11000, thecontroller 12000, theheater 13000, and thevaporizer 14000 may be differently arranged. - When the
cigarette 20000 is inserted into theaerosol generating device 10000, theaerosol generating device 10000 may operate theheater 13000 and/or thevaporizer 14000 to generate aerosol from thecigarette 20000 and/or thevaporizer 14000. The aerosol generated by theheater 13000 and/or thevaporizer 14000 is delivered to a user by passing through thecigarette 20000. - According to necessity, even when the
cigarette 20000 is not inserted into theaerosol generating device 10000, theaerosol generating device 10000 may heat theheater 13000. - The
battery 11000 may supply power to be used for theaerosol generating device 10000 to operate. For example, thebattery 11000 may supply power to heat theheater 13000 or thevaporizer 14000, and may supply power for operating thecontroller 12000. Also, thebattery 11000 may supply power for operations of a display, a sensor, a motor, etc. mounted in theaerosol generating device 10000. - The
controller 12000 may generally control operations of theaerosol generating device 10000. In detail, thecontroller 12000 may control not only operations of thebattery 11000, theheater 13000, and thevaporizer 14000, but also operations of other components included in theaerosol generating device 10000. Also, thecontroller 12000 may check a state of each of the components of theaerosol generating device 10000 to determine whether or not theaerosol generating device 10000 is able to operate. - The
controller 12000 may include at least one processor. A processor can be implemented as an array of a plurality of logic gates or can be implemented as a combination of a microprocessor and a memory in which a program executable in the microprocessor is stored. It will be understood by one of ordinary skill in the art that the processor can be implemented in other forms of hardware. - The
heater 13000 may be heated by the power supplied from thebattery 11000. For example, when thecigarette 20000 is inserted into theaerosol generating device 10000, theheater 13000 may be located outside thecigarette 20000. Thus, theheated heater 13000 may increase a temperature of an aerosol generating material in thecigarette 20000. - The
heater 13000 may include an electro-resistive heater. For example, theheater 13000 may include an electrically conductive track, and theheater 13000 may be heated when currents flow through the electrically conductive track. However, theheater 13000 is not limited to the example described above and may include all heaters which may be heated to a desired temperature. Here, the desired temperature may be pre-set in theaerosol generating device 10000 or may be set as a temperature desired by a user. - As another example, the
heater 13000 may include an induction heater. In detail, theheater 13000 may include an electrically conductive coil for heating a cigarette in an induction heating method, and the cigarette may include a susceptor which may be heated by the induction heater. - For example, the
heater 13000 may include a tube-type heating element, a plate-type heating element, a needle-type heating element, or a rod-type heating element, and may heat the inside or the outside of thecigarette 20000, according to the shape of the heating element. - Also, the
aerosol generating device 10000 may include a plurality ofheaters 13000. Here, the plurality ofheaters 13000 may be inserted into thecigarette 20000 or may be arranged outside thecigarette 20000. Also, some of the plurality ofheaters 13000 may be inserted into thecigarette 20000 and the others may be arranged outside thecigarette 20000. In addition, the shape of theheater 13000 is not limited to the shapes illustrated inFIGS. 1 through 3 and may include various shapes. - The
vaporizer 14000 may generate aerosol by heating a liquid composition and the generated aerosol may pass through thecigarette 20000 to be delivered to a user. In other words, the aerosol generated via thevaporizer 14000 may move along an air flow passage of theaerosol generating device 10000 and the air flow passage may be configured such that the aerosol generated via thevaporizer 14000 passes through thecigarette 20000 to be delivered to the user. - For example, the
vaporizer 14000 may include a liquid storage, a liquid delivery element, and a heating element, but it is not limited thereto. For example, the liquid storage, the liquid delivery element, and the heating element may be included in theaerosol generating device 10000 as independent modules. - The liquid storage may store a liquid composition. For example, the liquid composition may be a liquid including a tobacco-containing material having a volatile tobacco flavor component, or a liquid including a non-tobacco material. The liquid storage may be formed to be detachable from the
vaporizer 14000 or may be formed integrally with thevaporizer 14000. - For example, the liquid composition may include water, a solvent, ethanol, plant extract, spices, flavorings, or a vitamin mixture. The spices may include menthol, peppermint, spearmint oil, and various fruit-flavored ingredients, but are not limited thereto. The flavorings may include ingredients capable of providing various flavors or tastes to a user. Vitamin mixtures may be a mixture of at least one of vitamin A, vitamin B, vitamin C, and vitamin E, but are not limited thereto. Also, the liquid composition may include an aerosol forming substance, such as glycerin and propylene glycol.
- The liquid delivery element may deliver the liquid composition of the liquid storage to the heating element. For example, the liquid delivery element may be a wick such as cotton fiber, ceramic fiber, glass fiber, or porous ceramic, but is not limited thereto.
- The heating element is an element for heating the liquid composition delivered by the liquid delivery element. For example, the heating element may be a metal heating wire, a metal hot plate, a ceramic heater, or the like, but is not limited thereto. In addition, the heating element may include a conductive filament such as nichrome wire and may be positioned as being wound around the liquid delivery element. The heating element may be heated by a current supply and may transfer heat to the liquid composition in contact with the heating element, thereby heating the liquid composition. As a result, aerosol may be generated.
- For example, the
vaporizer 14000 may be referred to as a cartomizer or an atomizer, but it is not limited thereto. - The
aerosol generating device 10000 may further include general-purpose components in addition to thebattery 11000, thecontroller 12000, theheater 13000, and thevaporizer 14000. For example, theaerosol generating device 10000 may include a display capable of outputting visual information and/or a motor for outputting haptic information. Also, theaerosol generating device 10000 may include at least one sensor (a puff detecting sensor, a temperature detecting sensor, a cigarette insertion detecting sensor, etc.). Also, theaerosol generating device 10000 may be formed as a structure where, even when thecigarette 20000 is inserted into theaerosol generating device 10000, external air may be introduced or internal air may be discharged. - Although not illustrated in
FIGS. 1 through 3 , theaerosol generating device 10000 and an additional cradle may form together a system. For example, the cradle may be used to charge thebattery 11000 of theaerosol generating device 10000. Alternatively, theheater 13000 may be heated when the cradle and theaerosol generating device 10000 are coupled to each other. - The
cigarette 20000 may be similar to a general combustive cigarette. For example, thecigarette 20000 may be divided into a first portion including an aerosol generating material and a second portion including a filter, etc. Alternatively, the second portion of thecigarette 20000 may also include an aerosol generating material. For example, an aerosol generating material made in the form of granules or capsules may be inserted into the second portion. - The entire first portion may be inserted into the
aerosol generating device 10000, and the second portion may be exposed to the outside. Alternatively, only a portion of the first portion may be inserted into theaerosol generating device 10000. Otherwise, the entire first portion and a portion of the second portion may be inserted into theaerosol generating device 10000. The user may puff aerosol while holding the second portion by the mouth of the user. In this case, the aerosol is generated by the external air passing through the first portion, and the generated aerosol passes through the second portion and is delivered to the user's mouth. - For example, the external air may flow into at least one air passage formed in the
aerosol generating device 10000. For example, opening and closing of the air passage and/or a size of the air passage may be adjusted by the user. Accordingly, the amount of smoke and smoking satirsfaction may be adjusted by the user. As another example, the external air may flow into thecigarette 20000 through at least one hole formed in a surface of thecigarette 20000. - Hereinafter, an example of the
cigarette 20000 will be described with reference toFIG. 4 . -
FIG. 4 illustrates an example of a cigarette. - Referring to
FIG. 4 , thecigarette 20000 may include atobacco rod 21000 and afilter rod 22000. Thefirst portion 21000 described above with reference toFIGS. 1 through 3 may include the tobacco rod, and the second portion may include thefilter rod 22000. -
FIG. 4 illustrates that thefilter rod 22000 includes a single segment. However, thefilter rod 22000 is not limited thereto. In other words, thefilter rod 22000 may include a plurality of segments. For example, thefilter rod 22000 may include a first segment configured to cool an aerosol and a second segment configured to filter a certain component included in the aerosol. Also, as necessary, thefilter rod 22000 may further include at least one segment configured to perform other functions. - The cigarette 2000 may be packaged using at least one
wrapper 24000. Thewrapper 24000 may have at least one hole through which external air may be introduced or internal air may be discharged. For example, thecigarette 20000 may be packaged using onewrapper 24000. As another example, thecigarette 20000 may be doubly packaged using at least twowrappers 24000. For example, thetobacco rod 21000 may be packaged using a first wrapper, and thefilter rod 22000 may be packaged using a second wrapper. Also, thetobacco rod 21000 and thefilter rod 22000, which are respectively packaged using separate wrappers, may be coupled to each other, and theentire cigarette 20000 may be packaged using a third wrapper. When each of thetobacco rod 21000 and thefilter rod 22000 includes a plurality of segments, each segment may be packaged using a separate wrapper. Also, theentire cigarette 20000 including the plurality of segments, which are respectively packaged using the separate wrappers may be combined and re-packaged together using another wrapper. - The
tobacco rod 21000 may include an aerosol generating material. For example, the aerosol generating material may include at least one of glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol, but it is not limited thereto. Also, thetobacco rod 21000 may include other additives, such as flavors, a wetting agent, and/or organic acid. Also, thetobacco rod 21000 may include a flavored liquid, such as menthol or a moisturizer, which is injected to thetobacco rod 21000. - The
tobacco rod 21000 may be manufactured in various forms. For example, thetobacco rod 21000 may be formed as a sheet or a strand. Also, thetobacco rod 21000 may be formed as a pipe tobacco, which is formed of tiny bits cut from a tobacco sheet. Also, thetobacco rod 21000 may be surrounded by a heat conductive material. For example, the heat-conducting material may be, but is not limited to, a metal foil such as aluminum foil. For example, the heat conductive material surrounding thetobacco rod 21000 may uniformly distribute heat transmitted to thetobacco rod 21000, and thus, the heat conductivity applied to the tobacco rod may be increased and taste of the tobacco may be improved. Also, the heat conductive material surrounding thetobacco rod 21000 may function as a susceptor heated by the induction heater. Here, although not illustrated in the drawings, thetobacco rod 21000 may further include an additional susceptor, in addition to the heat conductive material surrounding thetobacco rod 21000. - The
filter rod 22000 may include a cellulose acetate filter. Shapes of thefilter rod 22000 are not limited. For example, thefilter rod 22000 may include a cylinder-type rod or a tube-type rod having a hollow inside. Also, thefilter rod 22000 may include a recess-type rod. When thefilter rod 22000 includes a plurality of segments, at least one of the plurality of segments may have a different shape. - The
filter rod 22000 may be formed to generate flavors. For example, a flavoring liquid may be injected onto thefilter rod 22000, or an additional fiber coated with a flavoring liquid may be inserted into thefilter rod 22000. - Also, the
filter rod 22000 may include at least onecapsule 23000. Here, thecapsule 23000 may generate a flavor or aerosol. For example, thecapsule 23000 may have a configuration in which a liquid containing a flavoring material is wrapped with a film. For example, thecapsule 23000 may have a spherical or cylindrical shape, but is not limited thereto. - When the
filter rod 22000 includes a segment configured to cool the aerosol, the cooling segment may include a polymer material or a biodegradable polymer material. For example, the cooling segment may include pure polylactic acid alone, but the material for forming the cooling segment is not limited thereto. In some exemplary embodiments, the cooling segment may include a cellulose acetate filter having a plurality of holes. However, the cooling segment is not limited to the above-described example and any other cooling segment that is capable of cooling the aerosol may be used. - Although not illustrated in
FIG. 4 , thecigarette 20000 according to an exemplary embodiment may further include a front-end filter. The front-end filter may be located on a side of thetobacco rod 21000, which is the side not facing thefilter rod 22000. The front-end filter may prevent thetobacco rod 21000 from being detached outwards and prevent a liquefied aerosol from flowing into the aerosol generating device 10000 (FIGS. 1 through 3 ) from thetobacco rod 21000, during smoking. -
FIG. 5 is a diagram showing an apparatus for manufacturing reconstituted tobacco, which includes a primary cutter and a secondary cutter, according to an exemplary embodiment. - Referring to
FIG. 5 , anapparatus 500 for manufacturing cut reconstituted tobacco may supply an initialreconstituted tobacco sheet 501 to a conveyor unit in a manufacturing process of the cut reconstituted tobacco. - The initial
reconstituted tobacco sheet 501 may be formed by agglomerating particulate tobacco obtained by grinding or pulverizing one or both of a leaf lamina and a tobacco leaf stem. Also, the initialreconstituted tobacco sheet 501 may include one or more traces of tobacco powder, tobacco fines, and other particulate tobacco by-products formed during the processing, handling, and delivery of tobacco. - The initial
reconstituted tobacco sheet 501 may include one or more endogenous binders, one or more exogenous binders, or a combination thereof to promote aggregating of the tobacco particles. - Also, the initial
reconstituted tobacco sheet 501 may include other additives such as tobacco fibers, non-tobacco fibers, aerosol formers, wetting agents, plasticizers, flavoring solutions, fillers, aqueous and non-aqueous solvents, and combinations thereof. The other additives are not limited thereto. - When the initial
reconstituted tobacco sheet 501 is used as an aerosol-forming substrate of a heated aerosol generating article, the initialreconstituted tobacco sheet 501 may have an aerosol former content greater than about 5% by dry weight. The initialreconstituted tobacco sheet 501 used for the heated aerosol generating article may have an aerosol former content between about 5% and about 30% by dry weight. - On the other hand, the initial
reconstituted tobacco sheet 501 may be manufactured through the following process. Tobacco raw material is first pulverized using a hammer mill, and the first-pulverized tobacco raw material is shifted to perform primary size separation. Further, the tobacco raw material is secondarily pulverized using a cutter mill, and secondary size separation is performed on the secondarily-pulverized tobacco raw material using a vibrating screen. Subsequently, the additive is mixed with the pulverized tobacco raw material, and after a process of refining and stirring, a slurry is produced. The slurry is thinned to produce the sheet, which is dried to produce the initialreconstituted tobacco sheet 501. However, a manufacturing process of the initial reconstituted tobacco sheet 50 is not limited thereto. - In an exemplary embodiment, the
apparatus 500 for manufacturing the cut reconstituted tobacco may supply the initialreconstituted tobacco sheet 501 to the conveyor unit using a feed roller. The conveyor unit may be a conveyor belt but is not limited thereto. - The
apparatus 500 for manufacturing cut reconstituted tobacco may include a primary conveyor unit that injects the initialreconstituted tobacco sheet 501 into theprimary cutter 510, and a secondary conveyor unit that injects each of a plurality of intermediatereconstituted tobacco sheets 511 through 513 into each of a plurality ofsecondary cutters 521 through 523. The number of secondary conveyor units may be determined based on the number of the plurality of intermediatereconstituted tobacco sheets 511 through 513. For example, when three intermediatereconstituted tobacco sheets 511 through 513 are manufactured via theprimary cutter 510, as shown inFIG. 5 , three secondary conveyor units may be included in theapparatus 500 for manufacturing cut reconstituted tobacco. - The initial
reconstituted tobacco sheet 501 injected into theprimary cutter 510 may be cut into a predetermined number of intermediatereconstituted tobacco sheets 511 through 513. In an exemplary embodiment, cutting edges may be arranged at the bottom of theprimary cutter 510. Furthermore, in another exemplary embodiment, theprimary cutter 510 may include two rollers that face each other. The two rollers may be rotated in opposite directions so that the initialreconstituted tobacco sheet 501 injected into theprimary cutter 510 may pass through theprimary cutter 510. A plurality of cutting edges may be arranged on an outer circumferential surface of each of the two rollers. That is, the initialreconstituted tobacco sheet 501 may be cut by the plurality of cutting edges while passing through theprimary cutter 510, so the plurality of intermediatereconstituted tobacco sheets 511 through 513 may be manufactured. - For example, in the
apparatus 500 for manufacturing cut reconstituted tobacco, three intermediatereconstituted tobacco sheets 511 through 513 may be manufactured by cutting the initialreconstituted tobacco sheet 501 using theprimary cutter 510. However, the number of intermediatereconstituted tobacco sheets 511 through 513 is not limited thereto. - The
apparatus 500 for manufacturing cut reconstituted tobacco may inject each of the intermediatereconstituted tobacco sheets 511 through 513 into thesecondary cutters 521 through 523 using the secondary conveyor unit. Thesecondary cutters 521 through 523 may be arranged downstream of theprimary cutter 510. Furthermore, thesecondary cutters 521 through 523 may be spaced apart from one another by a certain distance. - In an exemplary embodiment, the
secondary cutters 521 through 523 may be arranged in parallel with respect to theprimary cutter 510, in a stepped manner, or in a zigzag manner. However, the arrangements of thesecondary cutters 521 through 523 are not limited thereto. - In the
apparatus 500 for manufacturing cut reconstituted tobacco, the intermediatereconstituted tobacco sheets 511 through 513 are cut in a longitudinal direction using thesecondary cutters 521 through 523 so that a plurality of reconstituted tobacco strands may be manufactured in each of the intermediatereconstituted tobacco sheets 511 through 513. - Each of the intermediate
reconstituted tobacco sheets 511 through 513 may be processed into a plurality of reconstituted tobacco strands based on the cutting specifications set in thesecondary cutters 521 through 523. In an exemplary embodiment, the cutting specifications of thesecondary cutters 521 through 523 may set the number of reconstituted tobacco strands, but are not limited thereto. - On the other hand, the rotational force of the feed roller for supplying the initial
reconstituted tobacco sheet 501 to the conveyor unit may be different for each portion of the feed roller. For example, the rotational force of the feed roller may become weaker from the middle toward the edge of the feed roller. Thus, if the initialreconstituted tobacco sheet 501 supplied through the feed roller is directly cut in the longitudinal direction without being cut into a plurality of intermediatereconstituted tobacco sheets 511 through 513, there may be a difference in quality of reconstituted tobacco strands manufactured between the ones supplied by the middle portion and the ones supplied by the edge portion of the feed roller. This may result in a difference in the quality of cut reconstituted tobacco manufactured by cutting the reconstituted tobacco strands. - In the
apparatus 500 for manufacturing cut reconstituted tobacco according to the present exemplary embodiment, in order for the reconstituted tobacco strands manufactured from the reconstituted tobacco sheet supplied via the feed roller to have uniform quality, instead of directly cutting the initialreconstituted tobacco sheet 510 in the longitudinal direction, first, the initialreconstituted tobacco sheet 501 is cut into a plurality of intermediatereconstituted tobacco sheets 511 through 513 having smaller widths using theprimary cutter 510 and then each of the intermediatereconstituted tobacco sheets 511 through 513 is cut in the longitudinal direction using thesecondary cutters 521 through 523, so that a plurality of reconstituted tobacco strands may be manufactured. - Also, the
